Earlier quoted context omitted.
Disagree. A navigational aid such as Google Maps is only good as long as you know your exact destination in advance. If for some reason you can't, or you need to orient yourself in an area, or even understand the route you're on, or - God forbid - plan a trip involving multiple destinations - Google Maps is incredibly hard to use.
I'm not quite sure what you mean; I've been quite happy with Google Maps's support for multiple stops. And as for the other thing: "If you don't know where you are going, any road will get you there".
The latter two use cases are exactly what a map is supposed to be for. Hence, Google Maps suck at being a map.
